Answer:
False
Step-by-step explanation:
Natalie can return the washing machine without being liable for any replacement costs. Natalie is a minor, and minors cannot legally sign a contract except for purchasing necessities, e.g. food, clothes.
Since the washing machine probably had a significant cost, there should have been a written contract between the parties. The rental company should have requested Natalie some type of legal identification before renting the washing machine and signing the contract. Their only possible defense is that Natalie used a forged ID when she rented the machine, and that they were ticked by it.
But if the rental company cannot prove that Natalie tricked them using some fake ID, then Natalie has the right to void the contract and return the item. It doesn't matter if the washing machine suffered damages or not, Natalie is not liable for any reparation or replacement costs.
